Researchers have warned that obesity will become the biggest cause of cancer in women in 10 years.

There is already one of 12 new cases of disease associated with being
overweight or obese and this measure is set to increase smoking
cessation and stopping hormone replacement therapy.

Dr Andrew Renehan, a cancer expert at the University of Manchester, said: "Obesity is being moved to a level which makes it the largest cause related to cancer in women in 10 years."

In men, 3.2% of breast cancer was associated with being overweight or obese and 8.6% in women.
Colorectal cancer, breast cancer in postmenopausal women, and cancer endometrikal counted 65% of all cancer related to obesity.

Dr Renehan, from the University of Manchester, said: "I must emphasize
we are not trying to make a sensation about this. All of this is a very
conservative estimate, and the possibility of such numbers, in fact,
higher."

This may be related to the interaction between smoking, alcohol, excess
weight, and condition called back with acid drainage, but further
research is necessary to understand it cause.

Scientists are not sure why obesity may increase cancer risk, but
suspected it was related to hormones. As people put on weight, they
produce more hormones such as estrogen that helps tumors grow. People
who have a distended abdomen also has more acid in the stomach, which
can trigger cancer of the stomach, intestine, or esopagus.

Dr Renehan said the new strategy is needed to help people stay slim. "We
need to find a biological mechanism to help people find other ways to
overcome obesity," he said. "Just telling people to lose weight
certainly did not succeed."
